There's no question that the CHAdeMO quick-charging technology standard is a Japanese thing. But the Japanese government wants to take it global, and has thus disclosed more information about the CHAdeMO quick-charging technology standards as a way to encourage CHAdeMO adoption by more automakers. The Ministry of Economy, Trade and Industry would like to see the charging infrastructure grow and EV prices come down by encouraging more competition through a widespread charging infrastructure. Before the announcement, the standard was only available to some automakers and power companies. Some of the information that will be disclosed includes the shape of the plug that connects the car to the charger and how to prevent electrocutions, writes Green Car Congress, citing Nikkei. CHAdeMo uses 480 volts of electricity, so safety will continue to be an important issue to address.

Outside of Japan, the question of which fast charging technology will prevail is an open question. The new SAE Combo Charger design was unveiled earlier this year, but its exact standards have yet to be released. Still, most non-Japanese EV makers are embracing this technology rather than CHAdeMO. Right now, the only available mass-market EVs capable of fast charging with CHAdeMO are the Nissan Leaf and Mitsubishi i.

CHAdeMO was jointly developed by Toyota, Nissan and others, but Toyota has yet to take a stand on what fast charging technology will be used for the Toyota RAV4 Electric or other plug-in Toyota products. Most likely, it will be CHAdeMo for Toyota, joining ranks with the Japanese auto industry, versus U.S. and German automakers waiting for the SAE Combo Charger details to be announced. It has been a source of conflict between automakers.

      The new Toyota RAV4 Electric has no quick charge capability... just like the small battery Tesla Model S, that isn't out yet. That's a done deal.

        Wow, interesting. That is a strange choice. But I guess it if is just a limited issue compliance car, they don't feel they need to offer it.

          JakeY: I doubt Toyota had much choice in it. Tesla made the drivetrain and they aren't going to debut their DC charging solution on a vehicle without their name on it.

          Toyota has said they didn't add one because it wasn't clear which standard would dominate in the US. The next version (if they make it) will likely have a quick charge plug.

      CHAdeMO or SAE? It's a pissing contest with as much nationalism as well as money involved. Like Beta vs. VHS, the winner gets all the royalty.

      How did we manage to get in this mess in this day and age, talk about repeating the mistakes of the past.

      So where is the information about the standard?

      "Right now, the only available mass-market EVs capable of fast charging with CHAdeMO are the Nissan Leaf and Mitsubishi i." should be simplified to: "Right now, the only available mass-market EVs capable of fast charging are the Nissan Leaf and Mitsubishi i." no other cars currently uses any other standard for quick charging

        Doesn't the Tesla Model S have some sort of fast-charging though?

          The cars have the port ready. The chargers have not been publicly available yet (there have been spy shots of Tesla using them though). Elon has promised a supercharger announcement in September.

      I don't think lack of information is the issue. The issue probably has more to do with no wanting to pay license fees, wanting an integrated single plug instead of two plugs, . . . . . and probably slowing down the Japanese head-start in EVs so the US & German companies can catch up easier. Yeah that last one sucks but business is business.
